# `BB.Sensor.INA219.TestBot`
[🔗](https://github.com/beam-bots/bb_sensor_ina219/blob/main/test/support/test_bot.ex#L5)

Minimal robot for live-testing `BB.Sensor.INA219` against real hardware.

Not loaded by default — included in `test/support/` so it's compiled in the
`:dev` and `:test` envs. Run it from IEx:

    iex> BB.Sensor.INA219.TestBot.start_link([])
    iex> BB.subscribe(BB.Sensor.INA219.TestBot, [:sensor, :chassis, :main_bus])
    iex> flush()

# `child_spec`

```elixir
@spec child_spec(Keyword.t()) :: Supervisor.child_spec()
```

Returns a child specification for starting this robot under a supervisor.

# `robot`

```elixir
@spec robot() :: BB.Robot.t()
```

Returns the optimised robot representation.

This struct is built at compile-time from the DSL definition and contains:
- All physical values converted to SI base units (floats)
- Flat maps for O(1) lookup of links, joints, sensors, and actuators
- Pre-computed topology metadata for efficient traversal

## Examples

    robot = Elixir.BB.Sensor.INA219.TestBot.robot()
    link = BB.Robot.get_link(robot, :base_link)
    joint = BB.Robot.get_joint(robot, :shoulder)

# `start_link`

```elixir
@spec start_link(Keyword.t()) :: Supervisor.on_start()
```

Starts the robot's supervision tree.

## Options

All options are passed through to sensor and actuator child processes.
